This in line filter contains carbon for taste and odour improvement, plus a magnesium and calcium block to add beneficial minerals back when using RO to make drinking water.

This gives all the purification benefits of using Reverse Osmsosis, but returns the most important minerals to the water and makes it easier for the body to absorb.

It is a direct replacement for the in-line carbon on the majority of domestic drinking water RO systems, and can be added onto any RO systems using standard 1/4" tubing
